Novel carotenoid esters

The invention claims monoesters, diesters and multi-ester, the acid ester are part of alcohol are part of the beta-carotene compound. Two or more synthetic ester bond is carotenoids provides a novel compound, a beta-carotene and similar of the additive are. The novel of beta-carotene ester can be used as the antioxidant, a therapeutic agent, wherein the pigment or component as the colorant a domesticated fowl material. The polyester with the bottom of the distinct molecular conductive wire. The full method of beta-carotene (b) at least one of carboxyl beta-carotene esterification by at least one hydroxyl, beta-carotene or a preparation method of beta-carotene the reaction of the carboxyl carotenoid's acyl chloride. Preferably beta-carotene or a xanthophyl, zeaxanthin, kryptoxanthin, violaxanthin and are extracted from hydroxyl, beta-carotene and lycopene, different xanthophyl and dehydrogenation kryptoxanthin. Preferably carboxyl, beta-carotene is the roucou orange and β comprising roucou orange the promoter is a - 8 beta-carotene acid, crocetin; the promoter is beta-carotene a acid, carboxyl beta-carotene and red cuckoo element.
